A woman in San Francisco's Bayview district was hospitalized with life-threatening burns Sunday after police say a man she had been dating threw flammable liquid on her.

Officers responded to reports of a woman screaming near the intersection of Hollister Avenue and Jennings Street around 12:17 p.m. Sunday and found a woman in her early 20s who had been severely burned. The woman, whose identity was withheld by police, was rushed to the burn unit of St. Francis Memorial Hospital for treatment.

Oliver and the woman had been dating, police say. Although police did not offer a motive for the attack, they accused Oliver of throwing some kind of ignitable liquid onto her.

Oliver remains at large. Police described him as black, approximately 5 feet, 10 inches in height, weighing 155 pounds, and said he was last seen wearing a red-and-white hoodie jacket, gray-and-red Nike shoes and pajama pants decorated with multicolored shamrocks. Oliver also reportedly has a haircut with a fish design on one side of his head and a lightning bolt on the other.

Oliver is wanted on suspicion of attempted murder and arson, according to a San Francisco Police Department news release. Anyone who comes in contact with Oliver is asked to call the police.
